Touchstone File Setting

Setting Item

Notes

Create a Touchstone file

Deselected by default,

Touchstone file will be created if Zpv or Zpi is acquired.

If reference impedances are different among multiple ports, the Touchstone file that is prior to Renormalize will be created.
To do Renormalize, see [How to Renormalize] for more information

If selected,

Touchstone file will be created regardless of the acquisition of Zpv or Zpi.

(Note) Zpv is the characteristic impedance of the port obtained from the voltage.

To obtain Zpv, the integral path is required to be properly set to the port.
If the integral path is not set, Zpi is calculated from the current.

Reference Impedance

Sets the reference impedance of the Touchstone file if [Create a Touchstone file] is selected.

The entered value does not affect the calculation.

Output type of S-parameters

Selectable from Mag/Ang, Re/Im, or dB/Ang.

Mag stands for Magnitude, Ang for Angle, Re for Real, and Im for Imaginary.

Output S-parameters and Z-parameters at the same time.

If S-parameters can be output, text file of Z-parameters is output as well. (Project name.Results\Analysis model name.z*p)
